Scraper self-cleaning filter

The ZSG series internal scraper cleaning Filter, a type of Scraper self-cleaning filter, is mainly suitable for fluids with high viscosity and heavy particles in the filter belt。The XF-S2 series self-cleaning filter, which can be classified as a Stainless Steel Scraper Self-cleaning Filter, is specifically designed for the papermaking industry to solve the problems in coating and pulp filtration。It can remove paper breaks and streaks, effectively reduce the impact of emissions on the environment, and ensure working time and product quality to the greatest extent possible. This Outer Scraper Self-Cleaning Filter is fully automatic in its operation, making it an ideal choice for continuous filtration processes without the need for manual intervention。

The series self-cleaning filter is suitable for pipeline selection from DN25 to DN900, and its Fully Automatic Cleaning Filter feature ensures that the filtration process is not interrupted during cleaning cycles。This filter has the advantages of continuous fluid flow, easy maintenance, and reliable operation, so it is widely used in all industries. The automatic cleaning process is initiated by a pressure differential switch or pressure sensor that constantly monitors the pressure difference between the inlet and outlet of the filter, typically set at a preset value of 0.5 bar (7 psi)。The Scraper self-cleaning filter's operation principle is straightforward: a scraper, either inside or outside the filtering element, continuously removes solid material deposition from the screen's surface, ensuring the filter remains effective over time。

Operational principle

The working principle is that the liquid flows in from the inlet of the filter, from top to bottom, and flows through the surface of the Filter Element to the outlet; When a certain amount of impurities are collected on the surface of the filter element, the scraper of the motor driven assembly corrector rotates tightly against the surface of the filter element to scrape off the impurities. The impurities accumulate in the collection chamber along with the downward liquid. When a certain amount of impurities accumulate, the automatic drain valve opens the collection chamber to discharge the liquid containing high concentration impurities. The residual liquid can be recovered or discharged.
Note: Inner scraping type refers to the scraper being inside the filter element, while outer scraping type refers to the scraper being outside the filter element.
